Besides the possibility of simplification of the form of such basic facts like the Stratton-Chu formulas we obtain a criterion for the extendability of the electromagnetic field from a sufficiently smooth closed surface to its interior or exterior domain.In SpanishMathematical PhysicsComplex Variables30G35; 78A25text
